Hi,
Finally we can build out and load the libqt5.so successfully, but the loading
is still very slow because too many symbols are to be relocated.
Even many of these relocated symbols are inside the libqt5.so, we suppose they
should be resolved during the link time instead of loading time.
And

We, the doc team, would like to implement a change to how we document QML types

Currently, QDoc assumes things about the \qmlclass command that causes errors

Example usage: \qmlclass Item QQuickItem
For example, we advise

I would like to tidy up some more of the OpenGL support in Qt5. Throughout

Yes, the bottleneck of the loading now is the local relocations instead of
inter-library's.
So what we want to do will be reducing the number of local relocation.
Based on my understanding, this local relocation should be caused by the
symbol inter-positioning.
And from gcc option -Bsymbolic:

Arguably. We have to choose from the following:
1) Make Qt only target Lion+, drop Leopard support as well as any platform
without fine grained fs notifications
2)
4) put the functionality in an add-on, which has no requirement of supporting
all platforms, and allow people who need it link to it. It can live its life
there until a decent algorithm and API has been developed, and then we can
bring it in if we want.
